What is the use of purchasing carbon black after tire refining?
1. Make spherical carbon black and carbon black briquettes for heating and burning. Of course, such use will pollute the environment and is not recommended.
2. Pyrolytic carbon black is ground to N220, N330, N550 or N6660 to make fine carbon black, which is used back in the tire manufacturing industry for filling.
3. The pyrolysis carbon black of tires can be processed into color masterbatch and sold to the plastic industry for EVA foaming, PE blown film, plastic modules, etc.
4. Used as a pigment for offset printing inks, it can greatly improve ink dispersibility, fluidity, brightness, blackness and other properties.
Method for recovering carbon black from waste tires
The preparation of pyrolysis carbon black from waste tires is completely different from the commercial carbon black. To a certain extent, it needs to undergo a series of deep processing to achieve certain properties. The main processes include steel wire deep magnetic separation, ultra-fine grinding, and even Coalescent modification, wet granulation, drying and packaging and other processes, if necessary, according to the different tire sources and the previous preparation process, combined with the technical requirements of downstream applications, acid-base ash removal treatment is required.
What is the purchase market of carbon black after purchasing tires?
Many friends have such a question: Is the carbon black after tire refining easy to sell? In fact, the market for purchasing carbon black after tire refining is not bad. According to observations in the past two years, new manufacturers of carbon black from waste tires have emerged in many areas. The emergence of carbon black, and now pay attention to waste utilization, it can be seen that the purchase market of carbon black after tire refining is still good.
How much carbon black can be extracted from one ton of waste tires?
Under normal circumstances, 30%-35% carbon black can be extracted from one ton of waste tires, that is, 300 kg (kg) to 350 kg (kg) of carbon black.
Of course, I would like to remind everyone that the carbon black extracted from tires is not the same as the carbon black directly produced. Many industries cannot directly use the carbon black extracted from purchased tires, and need to be mixed with conventional carbon black. If I don't know how to use the carbon black refined from purchased tires. It is recommended not to blindly use the carbon black refined from purchased tires directly.
